Abstract

A Gram-stain-negative, aerobic, non-spore-forming, non-motile and rod-shaped bacterial strain, designated BSSL-BM3, was isolated from sand collected from a dune near the Yellow Sea, Republic of Korea, and subjected to a polyphasic taxonomic study. The neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strain BSSL-BM3 fell within the clade comprising the type strains of species. Strain BSSL-BM3 exhibited 16S rRNA gene sequence similarity values of 98.0–99.0 % to the type strains of , , , and and of 94.2–96.7 % to the type strains of the other species. The averagenucleotide identity and digitalDNA–DNA hybridization values between strain BSSL-BM3 and the type strains of , , , and were 82.2–88.8 % and 25.0–36.5 %, respectively. The DNA G+C content of strain BSSL-BM3 from genomic sequence data was 38.75 mol%. Strain BSSL-BM3 contained MK-6 as the predominant menaquinone and iso-C 3-OH, summed feature 3 (C 7 and/or C 6) and iso-C G as the major fatty acids. The major polar lipids of strain BSSL-BM3 were phosphatidylethanolamine and two unidentified lipids. Distinguishing phenotypic properties, along with the phylogenetic and genetic distinctiveness, revealed that strain BSSL-BM3 is separated from recognized species. On the basis of the data presented here, strain BSSL-BM3 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is BSSL-BM3 (=KACC 21632=NBRC 114502).
